Analog Input Module

Analog Input Module (F3AD04-0V / F3AD08-1V / F3AD08-4V)

Previous
High-speed accuracy conversion with excellent noise immunity

AD08

F3AD04-0V / F3AD08-1V
- The external input signal range is selectable from three ranges (0V to 5V, 1V to 5V and -10 to 10V)
- Four or eight inputs can be read and scanned as they are switched by multiplexer.
- Input filter and scaling processing functions allow processing of data into easily usable forms.
F3AD08-4V
- The input signal range is selectable from any of the following ranges: 0 to 20mA DC
or 4 to 20 mA DC
- A single module can accommodate eight input points.
- High conversion speed of 1 ms per point.
- Easy-to-use functions such as scaling and filtering.
